OpenText Dynamic Application Security Testing (DAST) is a cutting-edge, automated security testing platform that enables organizations to continuously assess live web applications, APIs, and services for exploitable vulnerabilities by simulating real-world attack scenarios. This solution operates directly on production or live environments without requiring source code or a staging setup, making it highly practical for fast-paced DevSecOps teams. It leverages advanced automation including macro generation and redundant page detection to reduce manual effort and enhance scan efficiency. The platform integrates seamlessly into CI/CD pipelines using REST APIs and provides an intuitive user interface for manual and automated test management. By tuning scans to specific application environments, OpenText DAST accelerates vulnerability detection and reduces false positives, helping teams focus on the most critical risks early in the development lifecycle. It covers a broad spectrum of modern web technologies such as HTML5, JSON, AJAX, JavaScript, and HTTP2 to ensure comprehensive testing of complex digital applications. Flexible deployment models include multi-tenant SaaS on public cloud, single-tenant private cloud, or on-premises, allowing organizations to align with their infrastructure and security policies. Enhanced scalability supports horizontal scaling for extensive testing needs, and client-side software composition analysis (SCA) improves detection accuracy. Organizations benefit from expert professional services to optimize deployment and maximize security outcomes. Overall, OpenText DAST empowers teams to safeguard software supply chains, improve application integrity, and accelerate secure software delivery.

Seeker® is a cutting-edge interactive application security testing (IAST) tool that provides remarkable insights into the security posture of your web applications. It identifies trends in vulnerabilities in relation to compliance standards such as OWASP Top 10, PCI DSS, GDPR, CAPEC, and CWE/SANS Top 25. Additionally, Seeker empowers security teams to keep an eye on sensitive data, ensuring it remains properly safeguarded and is not unintentionally logged or stored in databases without adequate encryption. Its seamless integration with DevOps CI/CD workflows enables continuous security assessments and validations for applications. Unlike many other IAST solutions, Seeker not only identifies security flaws but also verifies their exploitability, offering developers a prioritized list of confirmed issues that require resolution. By employing its patented methods, Seeker adeptly manages a substantial volume of HTTP(S) requests, nearly eradicating false positives and enhancing productivity while minimizing business risks. Furthermore, this comprehensive solution not only highlights security vulnerabilities but also plays a crucial role in effectively addressing and mitigating potential threats.

A revolutionary method for enhancing security in contemporary software development has been introduced. This technique integrates security measures directly into the development toolchain, facilitating the swift resolution of issues shortly after installation. Contrast agents continuously oversee the code and generate insights from within the application, enabling developers to detect and fix vulnerabilities independently of specialized security experts. This transformation allows security teams to focus more on governance and oversight tasks. Furthermore, Contrast Assess features an innovative agent that incorporates intelligent sensors for real-time analysis of the code. This internal monitoring minimizes false positives, which can be a significant challenge for both developers and security teams. By seamlessly integrating with current software life cycles and aligning with the tools used by development and operations teams, including compatibility with ChatOps and CI/CD pipelines, Contrast Assess not only simplifies security processes but also boosts team productivity. Consequently, organizations can uphold a strong security stance while optimizing their development activities effectively. This holistic approach marks a significant shift towards a more proactive and collaborative security culture in software development.

Veracode offers a comprehensive and adaptable approach to oversee security risks throughout your entire suite of applications. This singular solution uniquely delivers insights into the progress of various testing methodologies, such as manual penetration testing, SAST, DAST, and SCA, ensuring thorough risk management. Additionally, it enables organizations to maintain a proactive stance on security, thereby enhancing their overall application safety.
